FlowAlongSrf problem

Hello, I’m trying to put some boat mats into a 3d modelled boat but i cant seem to make the mat have the right curvature as the boat. I’ve tried flowalongsrf but either it turns the wrong way or does not fit exactly as i want it to. I don’t know what to do, I’m very new at this program.

All your target surfaces seem to be flat, you would just move them into place.

If you’re trying to use FlowAlongSrf your model is missing the “base” surfaces used to map your input to the output. See the help and the official training for how to use it.

Hello, the surface is curved upwards at the front.



I cannot seem to get the holes in the mat to line up with the holes on the boat. I have tried multiple different ways but can’t seem to make it align well.

all these surfaces marked yellow are planar, so you should be able to simply move them into place like Jim pointed out. If it doesn’t align it means something is off in the dimensions.

No it’s all flat surfaces, that curve is a ‘kink.’ Knowing how the command works, how are you handling that? Are you trying to do this all at once? what are you using for the “base surface?”

This is not how people model SeaDeck, they scan the boat and create the surface regions needed from the 3D, then unroll those surfaces and detail the 2D cutting pattern. It would have been very easy to just model this “in place.”

Hi Thomas, It looks to me that your mat is from another boat size. Without knowing the details such as edge relief it is hard to know how they should fit in the end. Another hacky way to try and get them close might be to use a Bounding box with a lot of control points so you can manipulate where you can. It is a lot of work , but as it’s been said, Model them in place is the best way. —Mark

I did not make the drawings, I got them sent to me so I was not able to make them from place which i would have done otherwise. I am only supposed to put the mats into the boat for the byer to see how it will look. And I have only worked with this program for a few weeks so I do not know very much.

Okay but FlowAlongSrf is simply not the tool for this. All the surfaces are flat, they can all be simply moved and rotated into position on the surfaces. FlowAlongSrf will potentially scale the objects, which is not what you want I think. It also seems like they maybe just don’t actually fit well.

You have a problem with the one piece that flows over a sharp kink, so…how is that going to work? Is it not that sharp on the real boat? To show what it will be like I would move it in to position on the main surface, then you will have to split it up at the kink and rotate it to fit the smaller end.
